TO-ALL WHOM lIT MAY GONCERN: l Be it known that I, ADOLPH OHLENSLAGER, oi` Jersey City, in the county of Hudson, and Stateof New Jersey, have invcntedaI new and useful improvement in.Ash-Pans for Locomotive Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, sufficient to enable persons skilled inv the art to make anduse the same, reference being had to the accompanying .dra-wings, making a part of this specification, I having assigned my whole interest in the` said invention and improvement to Henry L. Lansing and George H.A Chase, of the city of Buiialo, and State of New York. y

The nature of this invention consists, iirst, in an iron pan or box, provided with openings through the bottom, and a horizontal rotary plate, which has corresponding openings and solid portions, which may be rotated in a manner to nncovcr'the openings in the bottom of thepan, toA dump or discharge the ashes and cinders, and then closed so as to practically form a solid 'bottom and prevent the ashes and cinders from scattering upon the track, and thereby making an air-tight bottom; second, in the construction of central draughtfiue, passing centrally through thc'ash-pan; third, in the construction, application, and use of an adjustable valve.- capor damper' in connection with the central tiucgxvhich valve-cap has two distinetfeaturcs, to wit, a saucershaped cap, which may be raised and lowered in a manner to open and close the draught-flue, making it airtight when shut, and an inner inverted conical cap for spreading the incoming air and directing it equally over thc periphery oi' the valve-cap to the-tire; fourth, in dividing the ash-pan into four or more compartmentshaving inclinedl sides sloping downwardly to the openings through the bottom of the pan; fifth, in arranging a rock-shaft horizontally and passing in the recesses formed under the inclined sides, in combination with a vertical stem and link-connection, as a means of raising and lowering the valve-cap. In the accompanying drawings- Figure I is a vertical section of my improved ash-pan in one diameter taken in the line zum, Fig. III.

Lettersof like name and kind refer to like parts in each of the iigures.

A represents a locomotive ash-pan, which is made of cast iron and fitted to be supported under the tirey grate of a locomotive to catch and hold the ashes and cinders which drop from the fire. It is rectangular in form, and is divided into four or more compartments, having sloping sides ci c, so that the ashes and cinders which accumulate therein may easily slide downthe inclined sides and through the openings in the bottoni, when 'the openings are uncovered. Centrally within `the ash-pan is placed an air-supply or draught-flue, B. This flue may be cast with the pan, joining the compartments at the lower inner ends thereof. 'The openings through lthe bottom of the pan are between the compartments, and are shown at Z) Z1. On the bottom 'of the ash pan is placed a circular' .revolvingidisk-plate or gate, m, which has alternate openings and solid metal corres pending with the openings through the bottom of the pan, so that when the plate is revolved a quarter turn (more or less) in one direction the openings in the plate are made to coincide with the openings in the bottom of the pan, allowing the ashes and cinders to escape freely, and when revolved a quarter turn (more or less) in the opposite direction the solid parts of the plate are made to close the openings, so that no ashes or einders can escape, and also making it air-tight. This plate is connected -to the bottom of the pan by means of the flange-ring G and screw-bolts h. e is a vertical stem or rod,`\ vhich is connected with the horizontal rock-shaft d2 and with the valve-reap D. There is a jointed link-connection, z', between the valve-ste1n c and the rock=shat`t. The valve-cap D is fastened to the top of the stem c and is moved up and down thereby,- and shuts down a-ird tight on the top of the draught-tine.` There is an inner inverted conical cap, C', which has a hollow stem, c, slipping over the valve-stem c in a manner to fasten it to the valve-cap. This is for the purpose of spreading the incoming air and prevent it from lodging in the top of the valvecap and directing it equally over the periphery of the valve-cap to the tire. The roek-shaft-is Worked by the crank Z, by means of which the valve-cap may be raised and lowered and adjusted and opened little or more, so as te admit more orY less air to feed the fire, as may be desired. t is known to those acquainted with running coal-burning locomotive engines over railroads that thel ash-pans heretofore constructed are liable to drop ire and cinders upon the track, setting fire tothe road and other property, thereby causing great damage and destruction of property. It is also known that it costs much time, labor, and money to clean out the ash-pans. My improvement affords a. remedy for these evils. All the ashes and cinders which drop into the ash-pan while the locomotive is runningarc retained there (without the least scattering) until the engine arrives at the en'd of the trip, and thenthe ashes, vcindcrs,

dto., are easily and quickly dumped or discharged through the openings in the bottom of thc pan (by n quarter turn of the plate m) into a pit prepared for that purpose without expense or delay.

. What I claim as my invention, an'd desire to secure by Letters Patent, i'sl. A locomotive ash-pan, provided with openings b b through the bottom anda corresponding gate or diskplate, m, which may be moved andV placed in a manner to entirely close such openings when the locomotive is running and opened for the discharge of the ashes and einders at the proper time and place, substantially as and for the purposes set forth. f

2. An ash-pan for locomotives divided into compartments having sloping sides a a, for thc purposes and substantially as described. 1

3. The draught-flue B, passing-centrally through the ash-pan and the adjustable valve-cap D and inner inverted conical cap D', arranged and operating for the purposes and substantially as described.

4. The rock-shaft cl2, arranged in the recesses formed under the inclined sides, in combination with the vertical stem c and connecting-link z', as n. means ot'raising and lowering thc valve-cap, substantially. as deseribcd A. OHLENSLAGER. Witnesses:
